Convergent evolution - answer-Process by which unrelated organisms independently
evolve similarities when adapting to similar environments
The smaller the animal the ______ the SA/V ration - answer-Higher
Why do larger organisms need folding? - answer-The lower the SA/V ratio, the more
complex systems the organism needs to live. So large organisms need folding to fit
complex systems into their body
Why do more complex/large organisms need digestive organs? - answer-To store food to
use as energy later because they have a smaller SA/V ratio
What are the functions of these tissues:
- Epithelial
- Connective
- Muscle
- Nervous - answer-Epithelial: Covering
Connective: Connecting
Muscle: Movement
Nervous: Communication
Brief description of epithelial tissue: - answer-Epi- means above. Its above the other
tissues it's protecting (ex. lining on the inside of your blood vessels)
Cell are closely joined and shaped to fit it's function
, What are the types of epithelial tissue? - answer-Cuboidal
Simple columnar
Pseudostratified ciliated columnar
Stratified squamous
Simple squamous
Brief description of connective tissue: - answer-Connects and supports other tissues
Cells are scattered within a matrix
(A matrix can be liquid, jelly, or solid)
What are the types of connective tissue? - answer-Loose connective tissue
Cartilage
Fibrous connective tissue
Adipose tissue
Blood
Bone
Brief description of muscle tissue: - answer-Long fibrous cells that contract in response
to nerve signals (nervous tissue)
Mostly made out of contractile proteins
What are the types of muscle tissue? - answer-Skeletal
Smooth
Cardiac
Brief description of nervous tissue: - answer-Cells that connect to other cells to
transmit info to tell groups of cells to do certain things
